hole and into the guide tube. The
key and lock will engage with a
slight push and counterclockwise
turn. Some resistance will be felt
when turning the jack handle
assembly.

Tire change procedure
WARNING: When one of the rear wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the transmission is in P (Park) (automatic
transmission) or R (Reverse) (manual transmission). To help prevent
the vehicle from moving when you change the tire, be sure that the
parking brake is set and the diagonally opposite wheel is blocked.
WARNING: To prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite (other side and
end of the vehicle) to the tire being changed.
WARNING: If the vehicle slips off the jack, you or someone else
could be seriously injured.Roadside Emergencies

WARNING: Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack or changing the
wheel.
Note: Passengers should not remain in the vehicle when the vehicle is
being jacked.
1. Turn engine off and block the
wheel that is diagonally opposite of
the flat tire using the wheel chock,
if equipped. If the vehicle is a
4x4, lock the manual hub on the
wheel.
2. Remove the jack, jack handle, lug wrench and spare tire from the
stowage locations.
3. Use the tip of the lug wrench to remove any wheel trim.
4. Loosen each wheel lug nut one-half turn counterclockwise but do not
remove them until the wheel is raised off the ground.
The following steps apply to F–250/F–350 Single Rear Wheel
(SRW) vehicles only:
5. Insert the hooked end of the jack
handle into the jack and use the
handle to slide the jack under the
vehicle.
6. Position the jack according to the
following guides:
• Front (4x2) Roadside Emergencies

Never use the front or rear
differential as a jacking point.
WARNING: To lessen the
risk of personal injury, do
not put any part of your body
under the vehicle while changing a
tire. Do not start the engine when
your vehicle is on the jack. The
jack is only meant for changing
the tire.
7. Turn the jack handle clockwise
until the wheel is completely off the
ground and high enough to install
the spare tire.
8. Remove the lug nuts with the lug
wrench.
9. Replace the flat tire with the
spare tire, making sure the valve
stem is facing outward for all front wheels and single rear wheel vehicles.
If replacing an inboard rear tire on dual rear wheel vehicles, the valve
stem must be facing outward. If replacing the outboard wheel, the valve
stem must be facing inward. Reinstall the lug nuts until the wheel is
snug against the hub. Do not fully tighten the lug nuts until the wheel
has been lowered.
10. Lower the wheel by turning the jack handle counterclockwise.
Go to Step 19.
The following steps apply to F–350 Dual Rear Wheel (DRW) and
F–450/F–550 vehicles only:
11. Slide the notched end of the
jack handle over the release valve
and use the handle to slide the jack
under the vehicle. Make sure the
valve is closed by turning it
clockwise. Roadside Emergencies
